Standing in the centre of Preobrazhenskaya Ploschad (Transfiguration Square) is the Transfiguration of the Saviour Cathedral. The current version of the cathedral was built between 1825 and 1829 in the classical style. However the original version was built between 1743 and 1754 on the orders of Empress Elizabeth. During the Soviet period the cathedral remained open, although for a short period of time it was transferred to the Renovationist Church and several of its relics were removed. The cathedral was used as a bombshelter during the Siege of Leningrad.
